一. Purpose:
4-72 type centrifugal fan can be used as general indoor and ventilated take a breath of factories and large buildings, air transport and other not spontaneous combustion, harmless to the human body, the steel non-corrosive gases. B4-72 type fan can be used as a flammable volatile gas of ventilated take a breath. A viscous material, not allowed in the gas dust and hard particles contained no greater than 150 mg/cubic meter. Gas temperature shall not exceed 80 degrees Celsius.
B4-72 type fan performance and choose a size and foundation agree with 4-72, according to their choices. Same as the 4-72 type structure of the fan, motor selection and Y series of YB series.
二． Features:
air good performance, high efficiency and smooth operation.
